Looking after upright Yamahas in churches, under heavy use the pedal rod for the right pedal (metal cylinder, teflon end caps with metal pins) can fail. Once the top end insert gets loose it's pretty well toast. I replaced a couple of these metal dowels with good old fashioned wooden dowels and metal pins (half of a balance rail keypin works well, with the sawed end inside the dowel, of course.), FR punching on the bottom end, BR punching (thick) on the top end, bushing cloth strips in the lever hole for noise abatement. Since it's frequent to find exactly this setup in pianos over 100 years old, still working perfectly, one wonders why companies ever went to rubber bushings and teflon fittings, which often break or degrade in a decade or two.
